generator生成代码默认是去掉空行的,我们只需要直接删除EmptyStatement节点即可。 访问者代码为: const visitor={ EmptyStatement(path) { path.remove(); } } 运行后顺利删除了空行和空语句。 定义在一行的变量分离 还原前: var a = 123,b = 456; for(let c = 789,d = 120;false;); 现在需要将其还...
reportCode('debugger', 'Unexpected "debugger" statement'); t.end(); }); // statement should be removed so result is empty test('remove debugger: transformCode', (t) => { t.transformCode('debugger', ''); t.end(); });As you see test runner it is little bit extended 📼...

一、前言 js文件在日常测试中是一个容易被忽略的点,其代码繁杂冗长具有较差的可读性,但往往承载着重要业务逻辑,如前后端分离站点前端操作逻辑写在js中,开发者未对代码做安全处理直接发布便可能存在安全风险,而鉴于js代码的透明性,提高阅读难度似乎是最直接高效的办法 ...

for them to work together in the end we need to ensure somehow that one property gets mangled to the same name in all of them. For this, pass--name-cache filename.jsonand UglifyJS will maintain these mappings in a file which can then be reused. It should be initially empty. Example:...
抽象语法树(Abstract Syntax Tree),简称 AST,初识 AST 是在一门网页逆向的课程,该课程讲述了 js 代码中混淆与还原的对抗,而所使用的技术便是 AST,通过 AST 能很轻松的将 js 源代码混淆成难以辨别的代码。同样的,也可以通过 AST 将其混淆的代码 还原成执行逻辑相对正常的代码。
